The aim of this study was to evaluate the diagnostic performance of Simtomax(R) CoronaCheck, a serology rapid diagnostic test (RDT) for the detection of IgG and IgM against SARS-CoV-2. 48 plasma samples positive for SARS-CoV-2 based on RT-PCR and 98 negative control samples were studied. Diagnostic performance of the IgG/IgM RDT was assessed against RT-PCR and the electro-chemiluminescence immunoassay (ECLIA) Elecsys(R) Anti-SARS-CoV-2 total Ig. Overall, the RDT sensitivity was 92 % (95 % confidence interval [95 %CI]: 79-97), specificity 97 % (95 % CI: 91-99 %), PPV 94 % (95 % CI: 81-98) and the NPV 96 % (95 % CI: 89-99). When considering only samples collected >/= 15 days post-symptoms (DPS), the sensitivity increased to 98 % (95 %CI: 86-100) and the specificity was 97 % (95 % CI: 91-99 %). Two samples with 180 DPS were still positive for IgG. Globally, this IgG/IgM RDT displayed a high diagnostic accuracy for SARS-CoV-2 IgG/IgM detection in plasma samples in high COVID-19 prevalence settings. It could be effectively used, in absence of facilities for routine diagnostic serology, for samples with a DPS between 15 and 180 days.
